Hi, do you know if exists any module in python for series60 about cryptography?
I know that there's the md5 module but I'm serching an implemetation of cryptographic algorithms (like DES, RSA etc....). In python on PC there's a toolkit on cryptography but it seems very hard to use in python for series60.
Do you know any module to encrypt my infos in my cellphone?

You may like to look at pydes which implement DES
http://sourceforge.net/projects/pydes

I can't find a pure python asymmetric encryption
implementation. Does one exist?

[mueller-stach]

http://www.amk.ca/python/writing/pycrypt/

has most of the common cryptographic tools and is well documented.

SHA and MD5 is also available from pypy at
http://codespeak.net/svn/pypy/dist/pypy/lib/

Hi, I know pycrypt toolkit but I'm not sure that it works well under series60. In particular way I'm searching a solution to encrypt a SMS. Is it a good idea?

[petrib]

Why not. If you encrypt an SMS, then - naturally - the receiving end needs to know the keys and the algorithm used to decrypt it, too.

There's already a Series 60 app for that sort of thing; Fortress SMS: http://my-symbian.com/7650/applicati...Auto=503&faq=2

There'a some python crypot on siurce forge in the 'cryptopy' project. It includes AES. It was written for readability rather than speed, so it might be a little slow.

I'm yet working on cryptography in python series60. For this I'm considering "pycrypto toolkit" because it's a good framework. I've ported the directory structure of this framework into my N-Gage QD, but when I import a module it says that the module not exists.

I should install every python file "as a module" but this means that I'd change the dipendencies in the source of the framework....

Do exists a better solution to install all the framework as a single module?

I have just found an implementation of asymmetric cryptography (RSA).
http://cheeseshop.python.org/pypi/asym/
It's pure python. I haven't test whether it's fast enough yet.

get pycripto as as pys60 module will be a veeery good thing since a lot of pure python programs are written uppon this module, fist to all paramiko which is an implementation of ssh in python...
Probably we may consider to add this in the pys60 wishlist

I know there exists "Python Cryptography Toolkit": http://www.amk.ca/python/writing/pycrypt/

I also know that "quickie" has successfully compiled AES for Pys60: http://discussion.forum.nokia.com/fo...d.php?t=105215

After a quick look it seems to be possible to compile also some other modules from "Python Cryptography Toolkit" to Pys60. At least native RSA would be a nice addition. (Pure python implementations are quite slow...)

Is here someone who would be willing to help me in this "Python Cryptographic Toolkit for PyS60" project?

I think here: http://wiki.opensource.nokia.com/pro...S60_extensions
can be found some good examples (with sources) how to create the right directory hierarchy and .mmp/.pkg etc. files needed to compile .pyd-modules.

Or has somebody already done this?

Hello aaaapo ... sorry aaaaapo

I took a look on AES source code and compare with original source code. What a surprise there's no change !
So I suppose you can use the same process and add missing modules of the Py Cryptographic Toolkit like RSA and DES ...

Yes! I diff'ed the sources also, and they were the same!

But you are the one who compiled aes 1.0.0 3rd unsigned: http://discussion.forum.nokia.com/fo...8&postcount=12

Could you tell me which SDK, other tools and commands you used to produce above package?
